CCD Line Scan Cameras: Function and Application
CCD line scan cameras are semiconductor
cameras with one photosensitive line only. They
are used mainly for industrial applications. Line
scan cameras are used directly for determination of one-dimensional measures, e.g. width
of a gap, or in combination with a scanning
motion for acquisition of two-dimensional
images as, e.g. in fax machines and scanners.
Advantages of CCD line scan cameras such as
high optical resolution, high speed, and free
synchronization to individual line scans offer a
large variety of applications in opto-sensors
and measurement technology.
A selection of one- and two-dimensional applications is shown in the box below.
Optical resolution
Exposure means illuminance of the line scan
sensor for a set time period. The light sensitive
elements of the sensor transform radiation into
free charges. The time period of accumulation
of these charges during one exposure is called
integration time. The sensor is read out by
scrolling out the accumulated charges pixelby-pixel by means of a shift register. In continuous mode, the next exposure is started at the
time of read-out of the previous exposure. The
charges accumulated at each camera pixel are
transformed in voltage values for further
conditioning.
Pixel and line frequency
The optical resolution of a line scan camera is
given by the number of pixels (picture
elements), the photosensitive elements of the
line sensor. Line scan cameras with up to 12 000
pixels are available. In case of a scanning
motion, the resolution perpendicular to the line
scan camera is determined by the velocity of
scan and by the line scan frequency, i.e. by the
number of line scans per second. With line scan
cameras, substantially higher resolutions are
reached compared to conventional CCIR video
cameras. In case of drum-supplied material and
belt conveyors etc., line scan cameras offer the
additional capability of continuous endless image acquisition.

Exposure and integration time

The pixel frequency is the rate at which the free
charges are read out of the sensor. The
maximum pixel frequency is limited by the
individual sensor. The maximum pixel frequency determines, combined with the number of
pixels (plus a sensor-dependant number of
passive pixels), the minimum time required for
the read-out of a whole line scan – the minimum
exposure period.
The reciprocal minimum exposure period is the
maximum line frequency.
At cameras with integration control function the
integration time within a exposure period can
be truncated (shutter).
The maximum pixel and maximum line scan frequencies of the cameras available are shown in
the synoptical table on pages 10 and 11.

Interfaces for line scan cameras
Today Schäfter+Kirchhoff offers mainly digital
line scan cameras. In digital cameras the line
scan signal is digitized with 8 or 12 bit resolution
on the camera board directly. Some analog line
scan cameras provide downward compatibility. Digital CCD line scan cameras are provided
with GigE VisionTM, LVDS, CameraLink®, or
USB2.0 interface.
Schäfter+Kirchhoff now also supports the latest
industrial standard, the GigE VisionTM
interface. Scalability, flexibility, cable length up
to 100 m, and last but not least the availability
of competitive cables for network engineering
makes the GigE VisionTM standard interesting
for automation technology.
Cameras with LVDS interface are operated
with the Schäfter+Kirchhoff line scan grabber
SK9192D with PCI bus especially developed for
line scan cameras.
Signal processing such as run-length encoding, thresholding, windowing, and shading
correction are performed on-board and therefore do not need additional computing time. In
combination with the Schäfter+Kirchhoff merger box, multiple CCD line scan cameras are operated line-synchronously with a single line
scan grabber.
Cameras with CameraLink® interface fit
seamlessly into systems where CameraLink®
grabber is already used.
Cameras with USB2.0 interface are the prime
choice for mobile applications or for applications with changing PCs, e.g. mobile
measurement systems or educational experiments operated by a notebook.
A tabular overview of properties and connection possibilities of the different interfaces is
given on page 9.

CCD Line Scan Cameras: Selection Criteria
Blooming - Anti-Blooming
Selection criteria
Schäfter+Kirchhoff provides more than 50 different line scan cameras with black&white sensors or with color sensors. The large variety of
cameras offers an appropriate line scan camera for all measuring tasks. An overview of line
scan cameras available and their technical data
is shown in the synoptical table on pages 10
and 11. In addition to the criteria already noted,
i.e. number of pixels, maximum line scan frequency, and type of interface, there are selection criteria such as:
• Anti-blooming: Without anti-blooming saturated pixels, which can not accumulate
additional charges, transfer surplaus
charges, in case of further illumination, to
neighboring pixels. Bright, overexposed regions of the line scan signal are broadened.
Cameras with anti-blooming function drain
the charge excess (see below).
• Integration control: Without integration control the line scan frequency determines the
exposure time: while charges of a finished line
scan are read out, the next line scan is
exposed. The minimum exposure time is
attained at maximum line scan frequency.
Integration control corresponds to the function of a shutter. The accumulation of charges
is truncated previous to the finish of the line
scan period. In case of high light intensities,
over-exposures are avoided.
• Dynamic range and digitalization depth:
Depending on the sensor used, line scan
cameras are distinguished in their dynamic
range (signal to noise ratio). Some of the
digital line scan cameras can be operated
alternatively with 8 bit or 12 bit digitalization
depth (in 12 bit mode two bytes are used per
pixel, the maximum line scan frequency is
halved).
• Remote gain-/offset control: Many
cameras offer the capability of a software
controlled setting of signal amplification on
the camera side. This is mainly useful for balancing multiple line-synchronized line scan
cameras (e.g. using a merger box, see page
22). At cameras without remote gain /offset
control the internal camera signal amplification can be adjusted by a potentiometer at
the camera housing.
• Spectral sensitivity: Especially in case of
laser-based measurement systems, the
spectral sensitivity of the line scan camera
has to be accounted for (see below).

CCD line scan cameras with anti-blooming
sensor drain the charge surplus in case of overexposure via a ‘drain gate’. Neighboring, less
exposed pixels are not filled any more.
Depending on pixel frequency and spectral
range, overexposures up to a factor of 30 can
be drained.

Comprehensive software assistance is available for the start-up of cameras and the development of user software. The operating software SkLineScan allows for a rapid start-up of
the line scan camera systems. The oscilloscopic display of line scan signals is an ideal
tool for adjustment of the line scan camera and
for alignment of the optics (see page 6). With
the SkLineScan software all imaging parameters can be set and their effect on the camera
signal can be evaluated immediately. Acquisition of two-dimensional images is possible in
free-run mode or synchronized externally.
For the development of user software,
Schäfter+Kirchhoff offers SDKs with DLLs and
C++ class libraries for LVDS, GigE Vision™ and
USB2.0 cameras.
Supported are the Windows® operation
systems XP/2000/NT. For LVDS and USB2.0
systems, Linux® driver and tools are available
(GigE VisionTM projected).
In case of LVDS and analog cameras, downward compatibility to older Windows® versions
and to DOS is maintained by software.
For software development with LabView® a
VI-library is available. For developing user software for CameraLink® systems the software
development kit (SDK) of the grabber producer
is utilized.
Detailed information for software support is
given on pages 8 as well as on page 13 (GigE
VisionTM), page 15 (USB 2.0), page 17 (CameraLink), and pages 24 - 25 (LVDS).

Depending on the active sensor length and on
the magnification used, different types of lenses
are used:
The table on page 10 and 11 gives a general
idea of appropriate lenses. More details, technical data and formulas for lens selection are
given on pages 37 to 40.
Besides lenses, focus adapters and extension
rings are offered.
If desired, we assist prospective customers in
their selection of optics. In most cases, few
parameters of the measuring task are sufficient
for recommending the most suitable optical
system.

Pixels which are saturated caused by overexposure, i.e. cannot accumulate more
charges, partly transfer their charges to neighboring pixels. This effect is called blooming.
Blooming leads to corruption of the
geometrical mapping between signal and

Start-up of CCD Line Scan Camera Systems
System adjustment with oscilloscopic display
The sensor of a CCD line scan camera is onedimensional. The image of a CCD line scan
camera is made up of a single line and represents the brightness profile of an object
line imaged to the sensor line. The oscilloscopic display plots the digitized brightness
profile versus the sensor length in a x/y-plot
with high refresh rate. The y-axis represents
the signal intensity and the x-axis the sensor pixels. The scaling of the y-axis depends
on the resolution of the A/D converter – at 8
bit the scale covers 0 to 255, at 12 bit the
scale covers 0 to 4095. The scaling of the xaxis corresponds to the pixel number in the
line sensor.
The oscilloscopic diagram of the line scan
camera is an ideal tool for tasks such as the
adjustment of the lens aperture and integration time, for focusing the image, evaluation
of the object illumination, and aligning the
line scan camera. Due to a high refresh rate
changes in the optical system and of the
camera settings are visible immediately.

allows for a pixel-specific evaluation of the
line scan signal (see figure at the right).
The oscilloscopic display as well as the easy
to handle zoom function are integrated in the
line scan camera operating software SkLineScan made by Schäfter+Kirchhoff. Dialog
boxes for camera parameter settings allow
for an interactive adjustment of the CCD line
scan camera.
SkLineScan is part of the software package
available as versions for GigE VisionTM,
LVDS, USB 2.0, and CameraLink line scan
cameras (see pages 8).

peaks, the high-frequency crystal structure is visible below.
Aperture setting and integration time
The strength of the line scan signal is adjusted ideally, when in the brightest region of
the object the corresponding signal equals
approx. 95 % of the maximum signal. In this
case, all available gray values (255 at 8 bit
digitizing, 4096 at 12 bit digitizing) are used
to full capacity and overexposure is avoided
as well.
The intensity distribution of the line scan
signal is affected by the illumination intensity, by the aperture setting, and the camera
integration time. Beside the intensity, the
aperture setting influences the depth of field
and the quality of the image.
In case of a large F-number (small aperture),
the intensity is small and the depth of field
large. In case of small F-number (large aperture) the intensity is large and the depth of
field is small, see page 39, formula F8 and
F9.
In most cases best imaging quality is
reached by closing the lens aperture by one
or two steps, see page 39, F11.

Start-Up of CCD Line Scan Camera Systems
Shading correction and white balance
All lenses show vignetting, which depends on
the angle of field (see page 39, F10). Hence,
even with homogeneous object illumination the
imaged intensity decreases with increasing image height.
Shading correction (or flat field compensation)
is used to compensate for lens vignetting as
well as for inhomogeneity of the illumination.
For this purpose the object is temporarily
covered by a homogeneous white calibration
target. At initialization the shading correction
determines a gain for each individual pixel,
scaling each value to a normalized maximum
signal. Accordingly, the oscilloscopic display
shows a homogeneous intensity distribution
along the entire line sensor.
In case of color line scan cameras, the shading
correction is used additionally for white
balancing. The different sensitivities of the
sensors’ individual color channels are
compensated for as well as inhomogeneous
colors of the illumination.
In the SkLineScan software, functions for
shading correction and white balance are available for the user.
For software engineers, library functions for
shading correction and for white balance are
available in the SDKs for all interface systems.

Sensor Alignment
In case of line-shaped illumination, rotating the
line sensor results in asymmetric vignetting.
While monitoring the object illumination with
the oscilloscopic display, camera and illumination optics are aligned to each other properly.

Lens focusing with the oscilloscopic signal plot
To focus a line scan camera system, in principle
the oscilloscopic display is used, even in case
of two-dimensional measurement tasks. To
evaluate the focus, the edge steepness at darkbright transitions and the modulation of the line
scan signal are used (see figure on the right).
Focusing is performed with completely opened
aperture, in this case the depth of field is small
and the sensitivity of focus with change of focus
setting large. If necessary, the signal amplitude
has to be trimmed, e.g. by shortening the integration time.

• Sample programs in C/C++
• Configuration tool for CameraLink cameras (page17)
• Operating systems Windows XP/2000, Linux
Software development kit (SDK)
SkLineScan program
All software products by Schäfter+Kirchhoff include the software
SkLineScan, with control and display functions particularly designed for
line scan cameras. A substantial characteristic is the oscilloscopic display of the line scan camera signal. A With high repetition rate, the
intensity is displayed against the pixels in an x-y-plot. Changes of the
optical system (focus, aperture stop) as well as the camera parameters
(average time) become immediately visible. The program is an important tool for start-up and adjustment of the line scan camera system.
The graphical user interface of the program is identical with all interface
systems. For CameraLink line scan cameras the SkLineScan program
is available for selected grabbers *).
For programming the line scan cameras
and developing user applications,
Schäfter+Kirchhoff supplies
an SDK for line scan cameras *) Reference grabbers: NI PCI-1428, CORECO X64-CL iPro, microEnable III
with GigE, USB 2.0, and
LVDS interface. For line
scan cameras with CameraLink interfaces, the A
SDK of the grabber manufacturer*) has to be used.
The SDK contains the class
library Csk for C++ as well as
API DLLs. The function names are
to a large extent alike between the different interface systems, so that porting between the systems is easily
possible. The provided sample programs in C/C++ can be used as templates for the development of own applications. Source comments and
Functions in the SkLineScan program
a manual facilitate the programming of the cameras.
VI library for LabVIEW, NI Vision integration
An extensive VI library supports the control of line cameras with GigE,
USB 2.0 and LVDS interface under LabVIEW. With a few clicks a line
scan camera application can be built. For use of the VI library, the
respective driver is required.
For signal and image processing, the VIs and/or routines of the NI Vision
software can be integrated in line scan camera applications.

CCD-Line Scan Camera with
Vision™ Interface
The standard GigE Vision™ uses the large bandwidth of the Gigabit Ethernet of 1000 Mbit/s for
a fast and secure transfer of video and control data between camera and PC. Transfer distances
up to 100 m are possible. Data acquisition is performed in the PC or in a laptop. An additional
frame grabber is not required. All GigE Vision™ line scan cameras made by Schäfter+Kirchhoff
can be synchronized externally.
In multi-cast mode, networking of several cameras and distribution of image data to several networked computers offers a large variety of new possibilities for industrial imaging processing.
The capability of Gigabit Ethernet and the use of low-priced and commonly used network components make the GigE Vision™ standard very interesting for the industrial image acquisition
and automation.

SK6288GKOC
mono- Digital monochrome line scan cameras with 512 to 12 000 pixels per line and
chrome with 8 bit or 12 bit resolution. Data transmission is realized with a maximum
Color
data rate of 60 MHz. The cameras are primarily equipped with anti-blooming and integration
control function.
SK1024GTI
SK2048GTL
Digital b/w line scan cameras with TDI sensors. The sensors are working at 4096
pixels per line, and 96 stages. The resolution of the video signal amounts to 8
bit, the maximum data rate reaches 60 MHz. The cameras are characterized
by their anti-blooming feature and a very high dynamic range. Due to their
working principle, the TDI cameras have a sensitivity nearly 100 times higher
compared to conventional line scan cameras.

SDK for GigE line scan cameras
Software package SK91GigE-WIN
The software package
SK91GigE-WIN for WinGigE SK7500GTO
dows XP/2000 includes
the SkLineScan® soft1
ware for a rapid startup of
the GigE Vision™ camera,
the configuration tool
SKGigEConfig, as well as
a software development
kit (SDK) with DLLs and
class libraries for development of application
software.
The SkLineScan® software automatically recognizes the connected line scan cameras. The oscilloscopic display of the line scan signal 1 with
zoom function is an important tool for aligning the optical system. Non-modal dialogs for the
control of integration time, gain and offset settings allow the online configuration of the camera.
The SDK with DLLs and a class library for C++ offers easy to handle methods for the development of user software. Example codes and documented source codes of the operating programs
help getting started with programming.
SkLineScan GigE SK7500GTO
Configuration program SkGigEconfig
With the configuration
program SkGigEconfig
the GigE line scan camera
parameters e.g. gain, offset, and pixel frequency
are adjusted by camera
commands. Furthermore
current parameters as
well as specific product
information can be read
out from the camera.
The parameter settings
are stored on the camera
board and remain valid for the next operation even after shut down.
Synchronization
S12-13_CCD-ZK_GigE_E • Page 13
LINE-SYNC Modi
intern Mod. 0: FreeRun. The camera board
internally controls the trigger point and the
exposure time of the line scan. After completion of the line scan the next scan is
started automatically.
extern Mod. 1: The line scan exposed at the
time of the external trigger is read out. Start
and time of exposure are controlled internally by the camera. The exposure time is
programmed before. The trigger clock does
not affect the exposure time.
extern Mod. 4: A new exposure ist started
exactly at the time of triggering. The exposure time programmed is not affected by the
trigger clock.
Sync divider: Divides the external trigger
frequency by a programmed integer. Only
every n-th line is recorded.
FRAME-SYNC Mode
In addition, the GigE line scan cameras have
an external frame synchronization (FRAMESYNC) for synchronized acquisition of 2D
scans. The individual line scans are
synchronized internally or externally.
The camera suppresses the data transfer
until a falling edge of a TTL signal occurs at
’FrameStart’ input. (controlled, e.g. by a light
barrier).
Not until then is the ‘VideoValid’ set to active and the entire image data transferred via
GigE to the PC memory.

Configuration program SkCLconfig
Camera commands
With the configuration
program SkCLConfig by
Schäfter+Kirchhoff, line
scan camera parameters,
e.g. gain, offset, and pixel
frequency, are adjusted
via serial interface of the
CameraLink
interface.
For this the software uses
the clser***.dll, which is
attached to all CameraLink grabbers. In case the
program finds different
clser*.dll installed before,
the desired DLL is chosen
with ‘select’. The parameter settings are stored on camera board and remain valid for the next operation even after
shut down. The software SkCLConfig is included in the shipment of the camera.
Operating program SkLineScan,oscilloscopic display
For the camera operation and development of application software, the software development
kit (SDK) of the grabber manufacturer has to be used. Generally, common CameraLink grabbers
and their associated software are mainly designed for area cameras and do not support line scan
diagrams. For selected grabbers, Schäfter+Kirchhoff supplies the operating program SkLineScan® with oscilloscopic display for plotting line scan signals with zoom function and for online
camera parameter setting in order to set up the optical system conveniently. Reference grabber:
National Instruments PCI-1428, CORECO X64-CL iPro, microEnable III, SiliconSoftware.
SkLineScan microEnable III SK7500CTO

Oscilloscopic display:
Tool for the adjustment of
focus and aperture setting, as well as for evaluating the field flattening
of the lens. Zoom function for the display of
each individual pixel. Optionally: Adaptation of
SkLineScan to other
CameraLink grabbers is
possible.

CCD Line Scan Cameras with LVDS Interface
SK512ZSD
SK5150ZJR
monochrome
Data transmission with CCD line scan cameras with LDVS interface is executed based on the
standards of the Low Voltage Differential Signaling (LVDS). Due to the low voltage level of 3.3 V,
line scan cameras with this interface keep a low power consumption even at high transmission
rates. Camera control and data transmission to PC are accomplished with a PC interface board
(PCI bus), which also manages the power supply of the line scan camera. A separate power supply unit is not necessary.
For the synchronous processing of several line scan cameras with one PC interface the merger
box SK9195 is used.
mono- Digital monochrome line scan cameras with 512 to 12 000 pixels per line and

Line scan camera interface boards supply
the control signals and the supply voltages
for the operation of the CCD line scan cameras. As interface between PC and camera
they transmit the line signals to the PC
memory and allow setting the parameters of
the camera (integration time, pixel frequency and line scan frequency, synchronization).
Special pre-processing functions on-board
accelerate the signal evaluation in the PC
(shading correction, windowing, thresholding).
Library functions from the software package

Exposure
• Exposure period: The time in which the
charge carriers are read completely from the
shift register of the sensor (also exposure
time). The time interval is determined by two
successive SOS signals. The reciprocal value
is the horizontal frequency.
• Integration time: Duration of the charge
accumulation on the sensor in an exposure
period. By inactive integration control function the integration time is equal to the exposure time.
• Integration control: In case of CCD line scan
cameras with integration control function the
integration time can be programmed shorter
than the exposure time (shutter operation).
The line frequency remains constant.

Output
MCLK
Synchronization
The PC interface board generates the signals
for triggering an exposure. In free-run mode,
immediately after acquisition of one scan the
next scan is triggered. In case of external synchronization the clock of an external TTL signal and the mode of synchronization selected
determines the time of data acquisition. The
LINE-SYNC modes are used for synchronization of single line scans, the FRAME-SYNC triggers a whole 2D scan.
LINE-SYNC Modi
intern Mod. 0: Free-Run. The camera board
internally controls the trigger point and the
exposure time of the line scan. After completion of the line scan the next scan is started automatically (free-run).
extern Mod. 1: At the time of an external trigger, the readout of the line scan previously
exposed is performed. Start and time of exposure are controlled internally by the camera. The exposure time is programmed before. The trigger clock does not affect the
exposure time.
extern Mod. 2: At the time of trigger, the current exposure is aborted and a new exposure
period is started. The line exposed is read out
in the next cycle. Delays of up to 2 line cycles
are possible.
extern Mod. 4: Exactly at the time of trigger
a new exposure is started. Each line scan is
acquired (combines the advantages of mode
1+2, for integration control cameras only).
extern Mod. 3: The camera exposure is started by a software operation.
asynchron (ExtSOS): The exposure time is
determined independently from the interface
board setting by an external trigger. The computer clock or an external TTL signal can be
used as time reference. Exposure times of
any length are possible.
FRAME-SYNC Mode
In addition, the digital interface boards have
an external frame synchronization (FRAMESYNC) for synchronized acquisition of 2D
scans with an arbitrary number of lines. The
individual line scans are synchronized internally in the free run mode (0) or externally
(mode 1 or 4).
The interface board suppresses the data
transfer until a falling edge of a TTL signal occurs at ‘FrameStart’ input. (controlled, e.g.
by a light barrier). Not until then is ‘VideoValid’ set to active and the entire image data
are transferred via FIFO to the PC memory.

Detailed information see page 22
The video signal digitized by the camera is grabbed by the
interface board and transmitted to the PC memory. The
SkLineScan program displays the signals with 8 bit or 12 bit resolution. With an 8 bit resolution 256 gray scales are obtained. In the lower picture part the gray scaled line signal CCD is
illustrated, on top a zoomed part of the signal. With the zoom function each single pixel from
the complete measuring range can be displayed. Thus the image quality of the lens as well
as the proper illumination can be checked.
Gray scale processing
The interface boards support an adjustable signal threshold
(upper picture). Thresholding generates a binary signal. The
result of the operation is shown below: Signal smaller than threshold yields 0, otherwise 1.
Only if the signal reaches the threshold or falls below the threshold is a value stored in the
FIFO memory (RLE). Thereby the data volume per line is reduced and the measuring frequency
is increased. The complexity of edge position determination is reduced to masking of the
pixel addresses only.
Thresholding
The noise suppression logic, adjustable from n = 0 to 7 pixels
(see table), inhibits all threshold transitions which do not remain steady for at least n +1 pixels (e.g.: a setting on 3 pixels selects at least 4 pixel wide
transitions). The following application provides an example of this digital low-pass filtering
without reduction of the optical resolution: Checking of filter webs for holes too large in transillumination, with digital suppression of the regular web structure, which is also imaged with
high resolution.
Noise suppression
This function compensates for a non-uniform illumination of
the line sensor as well as possibly different sensitivities of
the individual pixels. An individual amplification factor for each pixel is stored in a memory
module on the interface board. The color line scan cameras with sequential RGB signal uses
the shading correction for adjusting the different sensitivities for R, G and B (white level balance). Upper graph: before shading correction, lower graph: after shading correction.
Shading correction
The window function defines a freely programmable window (ROI) on the line sensor. Only the pixel information within the window reaches the FIFO. Therefore, only these ranges have to be illuminated. The
Window function reduces the data volume and reduces the effort for line or picture evaluation. LineValid is a special form of a window function on interface boards for digital line scan
cameras with LVDS interface. With LineValid the window is set precisely along the active pixels of the sensor.

Advantages of the Merger Box SK9195
• Parallel and synchronous data acquisition with several line scan
cameras (no multiplex operation).
• Only one interface board is required by which costs and computer
resources are reduced.
• Reduced programming efforts.
• In operating mode 2: faster data acquisition. The line signals are
temporarily stored and transmitted to the PC interface board with
higher pixel frequency.
L1
L2

The line data of the connected cameras are stored temporarily and then
put out sequentially. Each line scan camera has a defined position within the combined signal.
For processing the data the individual camera signals can be separated in the computer and assigned unambiguously. This applies for linewise as well as for the block-wise evaluation of the camera signals. For
the temporary storage of the line signal of each camera an 8 kByte
internal memory (FIFO) is available inside the merger box.
The FIFO size and the adjusted operating mode of the merger box
determine the maximum pixel number of each single camera and those
of the sum signal.
After adjusting the operation mode (ex Schäfter+Kirchhoff or by the user)
the merger box configures itself. The type of the connected line scan
cameras is automatically identified. For the connection of more than
five line scan cameras several boxes can be cascaded.
A special extension connector (input of camera 5) can be configured allowing all cameras of the first and of the cascaded merger boxes to be
exposed at the same time and thus a pixel-synchronous data acquisition is also achieved with cascaded boxes.
An external power supply is necessary if the added power consumption of all connected cameras exceeds the allowed power
supply values of the PC interface board.

Operating modes of the Merger Box SK 9195
The pixel frequency of the PC interface board determines the pixel
frequency of the Merger Box SK9195 (max. 40 MHz). At this speed the
sum signal of the Merger Box will transmit to the interface board. The
pixel frequency of the connected line scan cameras is determined by
the selected operating mode of the Merger Box.
In operating mode 1 all line scan cameras work with the programmed
pixel frequency of the PC interface board.
In operating mode 2 a frequency divider reduces the pixel frequency
of the cameras by a factor 2, 3 or 4.
The operating mode and the frequency divider are adjustable by a
jumper.
Operating Mode 1: Single Buffered
Operating Mode 2: Double Buffered
The connected cameras operate with half, a third, or fourth of the programmed pixel frequency of the PC interface. The signals of all cameras are completely buffered and transmitted during the next line clock.
The sum signal arrives at the output of the Merger Box with a delay of
one exposure time (see example in fig. 6). An advantage of this operating mode is the possibility of connecting line scan cameras with a
lower pixel frequency specification to the Merger-Box and to transmit
the sum signal to the PC interface board with a pixel frequency two,
three or four times higher.
All connected cameras operate with the pixel frequency specified by
the programmed pixel frequency of the PC interface board. The pixel
frequencies of the line scan cameras and the sum signal of the Merger Box are identical. Data of camera 1 are directly transmitted to the
interface board, Subsequently the buffered data of the other cameras
follow (see example in fig. 5).
Line frequency of the sum signal
f=
pixel frequency of the output signal
totalized line length + 64
The maximum line frequency is determined by the camera(s) with the
lowest tolerable pixel frequency and by the maximum pixel frequency
of the interface board.
Maximum pixel length
The maximum pixel length of the connected cameras as well as of the
sum signal, is limited by the capacity of the Merger Box memory.
For buffering the line signals as a standard each camera disposes of
8 kByte FIFO memory (optionally 16 or 32 kByte).
In operating mode 1 the signal of the first camera is not buffered, thus
the maximum pixel length of the sum signal Lmax with n connected
cameras (n ≤ 5) is
Lmax= (n-1) · 8192 + (pixel length of camera 1)
The pixel length of the first camera is not limited by the existing FIFO
memory, to the other camera inputs line scan cameras with up to 8192
pixel each (with 8 bit video signal and 8 kByte FIFO memory) can be
connected
Attention: PC interface boards with full functional range (incl. Shading
Correction) can process line signals with a maximum length of 32768
pixel.
Example:
Combination of a 1024-pixel line scan camera with a 2048-pixel line
scan camera with pixel frequency of 40 MHz
Line frequency of the sum signal
The line frequency f, equal for all cameras, with n cameras calculates:
f = pixel frequency of the output signal
(longest line length + 64) · n
For efficient signal transmission, the usage of line scan cameras with
identical pixel lengths is appropriate.
Maximum pixel length
The maximum pixel length of the connectable line scan cameras in operating mode 2 corresponds to the half FIFO length in bytes, e.g. 4096
pixel with a standard FIFO capacity of 8 kByte. If a camera with a greater
pixel length is to be connected to one of the inputs of the merger box,
a version with 16 or 32 kByte, respectively, has to be selected.
The maximum length of the sum signal at the Merger Box output with
an 8 kByte FIFO memory calculates
Lmax = n x (FIFO in Bytes)/2 = n x 4096
n = number of cameras.

Programming
CCD line scan camera interface boards
The software package SK91PCI contains DLLs
and class libraries. On this base the user can create own application software under Windows XP
/ 2000 / NT SP4, Linux, and DOS.
Recommended programming platforms are MS Visual C++, Borland C++Builder under Windows and
g++ under Linux. The Windows-DLLs are usable
also under Delphi and LabVIEW.
Example programs and documented source
codes of the operating programs help getting
started with programming.
With the methods of the class libraries, the interface boards can be initialized and the line scan
parameters can be set comfortably. For example,
the method ‘CskCtrl::SetExposureTime’ with the
parameter ‘TimeMs’ programs the interface board
with optimal CS value and pixel frequency divider.
All on-board functions of the boards such as shading correction, window function, and threshold
processing are supported.

Shading correction
The SkLineScan® operation program controls the
shading correction automatically or manually.
Automatic mode: The program acquires some line
scans of a white calibration object. The averaged
pixel intensities are the reference for the shading
correction of the following scans. The shading correction scales the intensity of each pixel of the reference scan to 255 (8 bit resolution). Non-uniform
illumination as well as possibly different sensitivities are compensated (see figure 2b).
Manual mode: The user can set individual pixel
gains for the RGB lines of a color line sensor or for
odd/even pixel at b/w cameras.

Special hardware functions of the PCI bus
interface boards made by Schäfter+Kirchhoff
together with the SkLineScan® software offer
the user efficient solutions for realizing online
measuring tasks.
The DMA busmaster ability of the CCD line
scan camera interfaces permits continuous
acquisition of camera data with a CPU load of less
then 1% 3 . The CPU is free for other tasks such
as the evaluation of the camera data and control
of external devices. The data are written cyclically
into a physically connected memory area.
The DMA memory is divided into equally sized
blocks; the size is determined with a programmable number of lines n. The number of blocks is
at least two up to the number of lines in the DMA
memory, i.e., the smallest possible block size is
exactly one line.
While the interface board writes into a block, data
in other blocks can be processed. When a DMA
block is filled, an event and the virtual address of
the filled block are reported to the user.
With this virtual address the user can access the
camera data directly.

Multi object concept
In the multi object concept of the SkLineScan®
software, up to four data acquisition objects, each
having their own memory in the user’s range, can
be determined for each interface board. The size
of the memory areas can be different and in the
static operating mode can even have different

This method is suitable for continuous acquisition
and evaluation of line scan signals in small to medium block sizes. The interface board operates as
sensor without temporal limit and writes cyclically into the DMA memory in a ring buffer process.
During acquisition the user is connected online

Scatter/gather technique
The data memory for a 2D-scan is reserved in the
user layer. Preparing the DMA process the SK driver
in the scatter/gather procedure determines all
physical memory segments of the image buffer and
internally (kernel layer) stores their address and size
in a table (memory descriptor list - MDL). The scan
process is finished if all MDL entries were
processed. Then the image is completely in the 2Dscan buffer. The CPU is loaded with less than 4%.

DMA online operation
The CCD line scan camera interface boards of
Schäfter+Kirchhoff transport the digitized line
scan camera data in the busmaster DMA (direct
memory access) via the PCI bus directly in the
physical PC memory. Because Windows XP/2000/
NT are virtual operating systems, the user has no
direct memory access on the physical memory of
the PC.
The memory in the virtual address range, which
appears for the user as a cohesive memory, consists in real terms of many distributed segments of
the physical memory of the PC, whose sizes and
positions are determined by the operating system
and are not known a-priori. The software driver of
Schäfter+Kirchhoff determines these memory
areas and offers to the programmer comfortable
methods for the processing of camera data.

is less efficient as in the DMA online operating
mode.
Parallel operation of several interface boards
In a PC up to 4 interface boards can be operated
in parallel, and can be synchronized mutually.
In the busmaster DMA the PCI bus interface transfers the data immediately after their appearance in
the FIFO in double word blocks (= 4 pixels) into the
PC memory. Normally the FIFO will not overflow,
as the data transfer speed of 132 MByte/s is higher
than the pixel frequency of the CCD line scan
camera. If, however, several interface boards
operate parallel in one computer or the bus is busy
with other system activities, the FIFO can overflow,
and data can be lost. In a 2D-scan this leads to a
line displacement in an image. A FIFO-full-interrupt will be triggered.

Analog CCD Line Scan Cameras
Analog line scan cameras emit video data as
analog voltage values. For processing the video
data in a PC, the analog video signal is transferred via cable to the PC interface board where
it is digitized. After pre-processing operations
on-board, the digitized data are transmitted to
the PC memory, where further handling takes
place.

The Smart line scan camera SK2048IJR is a
stand-alone measuring system for measuring
widths and edge positions without connection
to a PC. The output of measuring data is done
via RS232 interface or analog. In addition, a
switching output indicates whether the measured width or edge position lies within a
previously defined range or not. Measured
values are read out via serial interface. The
analog output displays measuring data as voltage. The range maximum corresponds to a
voltage of 3.3 V. The camera starts with its
measuring task immediately after connection to
its power supply.

TDI Line Scan Cameras
Modular
interface concept
(Time Delayed Integration)
Line Scan Cameras with Time Delayed Integration
(TDI) technology have a sensitivity 96 times higher,
compared to conventional line scan cameras. Particularly in case of dim objects (e.g. wafer inspection with dark field
illumination) TDI cameras achieve significantly higher measurement and scan velocities. The pre-condition for use of a TDI camera is the movement of the test object in a preferential direction at a defined velocity (see below).

The principle of TDI technology is based on the time delayed
multiple exposure of a moving object. The sensor is composed
of 96 CCD lines, arranged in parallel. At the end of each exposure period the charges are shifted to the adjacent CCD line
(see fig. ‘charge transfer’). During the following exposure periods further charges are acquired and added to the already
existing charges, and their sum is again shifted to the next line.
Finally after 96 exposures the sum is put out as video signal.
Through an object movement synchronous (and parallel) to the
line-wise charge transfer, a 96-fold multiple exposure is actually achieved. After an exposure period, the object is hereby
moved far enough so that it is mapped trough the lens onto
the respective next sensor line, that is, where the charges from
the previous period were also transported.

Application TDI line scan cameras: dark field illumination
Dark field illumination
In industrial image processing, dark field illumination is particularly used for examination of
highly reflecting surfaces.The light beam under
a flat angle of incidence hits the surface of the
test object. The beam is reflected and misses
the camera lens. With
dark an immaculate surface
the
object
field appears completely
dark. At surface irregularities, e.g. scratches and cracks, but
dust, lint and dirt as
well, a small part of the
light is scattered diffusely towards the
lens and is displayed on the sensor. Tiny irregularities can be detected scarcely under the res-

olution limit of the lens. Equally to the observation of a fixed star, the image is not completely sharp anymore, however the elucidation
in the image is still noticeable.
Image acquisition with dark field illumination at
reflecting surfaces is typically faint. Therefore
with conventional line scan cameras substantially longer integration times have to be set,
compared to, for example, directed bright field
illumination (see page 34) or image acquisition
of a strongly vague reflecting object. This leads
to low horizontal line frequencies and low scan
velocity.
The highly sensitive TDI line scan cameras are
particular beneficial here. With the same illumination power considerably higher measuring
and scan velocities can be achieved.

Cameras with triple line and dual line sensors
The color line scan cameras provide the red (R),
green (G), and blue (B) information sequentially
in one single line scan signal. A two-dimensional
color image is generated by moving the object or
the camera. Thereby the sensor properties, the
travel direction, and the travel speed have to be
accounted for:

Triple-line
sensors
have 3 separate sensor lines for the primary colors red (R),
green (G), and blue
(B). With up to 3x
10680 pixels tripleline color line scan
cameras have an extremely high optical Pixel layout and line signal of a
3.5 µm triple-line sensor
resolution.
Pixel widths are – depending on the sensor –
3.5 µm or 8 µm. The distance in between the sensor lines is 8 times the pixel width.
Advantages: Very high optical resolution. Precise color mixing at line synchronous acquisition.

A true-colored image requires a white balance
operation (shading correction). For this the RGB
intensities are calibrated with a white calibration
target. Furthermore particularly with sources with
a high red or infrared portion (e.g. halogen lamps)
the usage of optical filters is appropriate (e.g.
UV/IR cut filter FBP-UVIR-..., see p. 40).

During object travel, an object point reaches the
blue CCD line sensor first. If the object is translated by one pixel width per cycle, after 8 line cycles the green pixels are exposed. After another
8 pixels the red pixels are reached and the full
color information is acquired completely. The color information originating from different object
points has to be buffered in the computer and afterwards relocated correctly. The PCI interface
board SK9192D (LVDS) and the SkLineScan®
software support corresponding functions.

2D acquisition with dual line color sensors
For 2D image acquisition with dual-line color sensor signals with 2048 x green, 1024 x red and 1024
x blue, there
are two different
alternatives.
1. All green
pixels generate an image
point. The red
and blue pixels are each used twice. 2048 image
points per line are generated.
2. The red and blue pixels are used only once and
combined with the mean value of two adjacent
green pixels. 1024 image points per line are generated. The image resolution is higher in alternative 1 because twice the green pixels are used.
Dual-line sensors have two sensor lines directly
bordering on each other. One sensor line has 1024
red and 1024 blue pixels alternately. The other
sensor line has 2048 green pixels. By internal
buffering of the red-blue line, the RGB pixels are
already accurately allocated in the camera.

CCD Line Scan Camera with
Bright Field Illumination
An innovative design for new applications in
surface analysis
Sealing surface
Coin testing
Micro embossing Lacquer damage
High-contrast image acquisition of structured objects; making the invisible visible
Illumination and image acquisition techniques well adapted to the object properties, emphasize
the object features of interest. Elaborate image processing algorithms are avoided.
Fig. 1: CCD line scan camera sensor
head with directed bright field illumination
In a directed bright field illumination the light
comes from the camera direction. Glossy surfaces parallel to the CCD sensor reflect most
of the light back to the camera and so appear
as bright areas. Structured surfaces and
beveled edges appear dark. Fig. 2 illustrates
the effect of the directed bright field illumination by use of a cross section of an euro coin.
Directed bright field illumination:
Principle

In microscopy, the application of sophisticated illumination techniques for the
enhancement of specific object features has been a matter of course for a long time.
It is well known, that, in addition to the performance of the lens, the illumination is crucial
for the quality of the image recorded. With incident light microscopy, e.g. for the
examination of the crystal structure of metallic surfaces, techniques such as bright field
and dark field illumination, directed and diffuse illumination are used since the end of
the 19th century.
Line scan sensor heads by Schäfter+ Kirchhoff
combine the line scan camera, the measuring
object and a LED based directed bright field
illumination in a ruggedized unit, well suited for
industrial applications. The LED illumination is
aligned with the camera lens and has service
life of several years.
By their modular structure CCD line scan camera sensor heads are used for various tasks in
surface and texture analysis. Figure 1 shows a
sensor head with 8 µm resolution with a field of

view of 33 mm (4096 pixels). Figure 1 on the
opposite side shows a sensor head with a resolution of 5 µm and a 41 mm field of view
(> 8000 pixels). The working distance in each
case is 50 mm.
Directed bright field illumination is optimally
suited for surface inspection. Surface damages, not noticeable to the human eye, are
made visible with high contrast. Subsequent
image processing encounters optimum conditions.

1 The edges of the mint margin and the figure are sloped inside and outside. The vertically directed light is scattered, only a part
is reflected back on the CCD sensor. The
edges are reproduced darkly.
2 Margin and figure face are arranged at
right angle to the illumination source, they
reflect most of light to the sensor and are
reproduced as bright surfaces.
3 The British islands and the European
continent have a face with structured grain.
The light is scattered and the European
continent is displayed as a dark surface
with bright granulation.
4 The transition of the coin margin to the
center surface is slightly bent and is rendered as a surface with gray tone.
A Identity card with blind embossing illumined diffusely: No significant textures of the
surface are visible.
B Shot with directed bright field illumination: Detailed and rich in contrast exposition
of the blind embossing.
C Detail view of section B The edges of
the individual embossing grooves scatter the
directed illumination and are seen as two parallel dark lines on the image. The flat surface
and the groove bottoms directly reflect the
light and are seen as bright areas in the image.

Fig. 4: Varnished aluminum test plate
with filiform corrosion along two
scratches.
Varnished auto body sheet steel made of high
alloy aluminum is sensitive to filiform corrosion and filiform varnish infiltration originating from scratches. The directed bright field
illumination reveals the full contrast of the
filament thus formed. The automatic evaluation of the test plates based on digital image
processing finds optimum conditions.

Lenses, Lens Adapters and Camera Mounts
Criteria for lens selection
The lens selection tables Table 1 to Table 3 on page 37 take the max. permitted length of the CCD sensor into account.
Video, photo, or scan and macro lenses respectively are suitable for a limited
sensor length and a limited range of magnification.
Further selection criteria for lenses are lens focal length, F-number, transmission, contrast, geometrical distortion, and the mechanical lens mount.
Video (CCTV-) lenses O1 with C-mount camera thread are available for
different sensor lengths.
• 1" for max. 15 mm sensor length,
• 2⁄3" for max. 11 mm sensor length.
CCTV lenses are characterized by a low F-number (F1.4 to F1.8) and small
size. They have an integrated focusing mechanism. Together with extension
rings A1 small reproduction scales are achieved.
Photo lenses: Photo lenses are suitable for CCD line scan cameras with
sensor lengths up to 36 mm. They have an integrated focusing mechanism
and stand out due to a good cost/performance ratio. Two type series are
provided:
Photo lenses series SK: O2 For industrial measuring systems Schäfter+
Kirchhoff provides a special series of photo lenses with focal lengths from
20 mm to 85 mm. A screw mount connects the lens housing with the body
of the CCD camera. This efficiently prevents a displacement of the measured signal on the CCD sensor (as with standard SLR lenses and standard
bayonet mount). A blocking bridge with integrated screws for fixation of focus and aperture setting secures the lens against unintentional misadjustment.
Standard photo lenses O3 with F-mount (bayonet mount): Schäfter + Kirchhoff provides series AF from Nikon .
For Photo lenses with bayonet mount (e.g. F-mount), Schäfter + Kirchhoff
provides a lens adapter A3 for connecting photo lenses (SLR lenses) with
bayonet mount to CCD line scan cameras with mounting thread M40 x 0.75
or M32 x 0.75.
Scan lenses O4 , unlike typical photo and CCTV lenses, are optimized for
a finite reproduction scale (β = 1/2 - 1/20). They are suitable for sensor lengths
up to 90 mm. In the specified magnification range these lenses have a high
imaging quality and a plane field of view. Hence, in case of macro imaging,
its use can make sense for CCD line scan cameras with short sensor lengths.
These lenses do not have a mechanism for focusing such as video and photo lenses do. The focus adapter FA22-40 A4 and optional extension rings
ZR type ZR10 - ZR50 ensure a precise and
mechanical stable connection between scan lens and line scan cameras
made by Schäfter + Kirchhoff.
Macro lenses O5 with focal lengths f’= 50 mm, f’= 75 mm, and f’= 120 mm
are optimized for magnification around 1:1 (0.8 to 3 times) and are suitable
for sensor lengths up to 43 mm, 70 mm, and 130 mm, respectively. These
lenses do not have a mechanism for focusing such as video and photo lenses do. The focus adapter FA22-40 A4 and optionally extension rings ZR
type ZR... ensure a precise and mechanical stable connection between scan
lens and line scan cameras made by Schäfter + Kirchhoff.
For cameras with screw mount M45 x 0.75 and sensor lengths up to 41 mm,
Schäfter + Kirchhoff provides extension rings ZR-L and focus adapter A5
with a large inner diameter in order to avoid vignetting. In this case, the focus adapter is placed directly after the lens.
Camera brackets and camera consoles: For all camera types Schäfter +
Kirchhoff provides camera brackets M3 and M4 ,which are fixed directly
to the camera body. In case of macro imaging with extension rings, camera
consoles M5 and M6 are used, which hold the camera centrally at the extension rings.
Cameras with screw mount M72 x 0.75 mm: This series is designed for
line scan sensors with lengths up to 52.5 mm. With focus adapter FA26S45 (see p. 32 and p. 38) camera body and scan or macro lens are joined
to a complete system.

Scan and macro lenses do not have a focusing mechanism. Hence, these
lens series are attached to line scan cameras with the adjustable focus
adapter FA22-... .
The focus adapter can be supplied with different screw mounts on the camera
side (from C-mount to M42x1), see order code. On the front side a thread
M39x1/26“ (Leica thread) allows for the adaptation of scan and macro lenses.
In the focus adapter, there is a fine pitch thread with 11mm range. The length
of the focus adapter can thus be varied from 22 mm to 33 mm.
On the circumference there are 3 pin screws for locking the adjusted focus
position.
Macro imaging requires a large distance between camera and lens.
Extension rings ZR..., graded in lengths from 10 mm to 5 mm, bridge this
distance (calculation see page 39, F4 and F5).

After selecting a CCD line scan camera, a suitable lens and, if necessary,
extension rings have to be determined. The required lens extension and the
depth of focus can be calculated exactly.
Calculation is performed in the following 5 steps:
Step 1: Magnification: For a given measuring range L and a selected line
scan camera with sensor length S, the magnification β is calculated, see
(F2).
Step 2: Focal length: With magnification and the given measuring distance
OO’ the focal length f of a suitable lens can be calculated, see (F3).
By contrast, with a given lens focal length f and a given magnification β the
required measuring distance OO’ can be calculated, (F6).
Step 3: Lens extension and tubes length: For achieving a sharp imaging
the lens has to have a defined distance from the CCD line sensor.
In case of CCTV lenses and photo lenses the lens extension ∆s, is calculated (F4), and set with the focusing mechanism.
In case of scan and macro lenses the lens extension ∆s is set at the external focusing mechanism. For large magnifications additional extension rings
are used.
The required tube length LT is calculated with (F4) and (F5). It is realized with
extension rings and - in case of scan and macro lenses - with the focus
adapter.
Step 4: Depth of focus: In case of imaging objects with certain thickness
the depth of focus 2z has to be determined. It has to be large enough in order to image the whole measuring object sharply. (F8).
Step 5: Resolution: A large F-number yields to a reduction of resolution
caused by diffraction. The resolution of the imaging has to be controlled,
F2: Magnification β:

Magnification β = 1/10.1 and OO’ = 605 mm:
Focal length f = 605 mm/ (10.1 + 2) = 50 mm
F4: Lens extension ∆s’
With the magnification β and focal length f, the lens extension is:
∆s’ = f ⋅β
Example 1: Magnification β = 1/10.1 and focal lenth f = 50 mm:
∆s’= 50 mm / 10.1 = 4.95 mm
Example 2: In a macro imaging with β = 1, (1:1 - imaging) the lens extension
equals the focal length f.
F5: Tube length LT
LT = flange focal length + lens extension - (distance CCD-camera flange)
LT = s’A + ∆s’ - s’K
Example: Rodagon 4.0/80, focal length f = 81 mm, β = 1/6,
s’A = 74.7 mm, s’K = 19.5 mm
∆s’= f/β = 81 mm/ 6 = 13.5 mm
LT = 74.7 mm + 13.5 mm - 19.5 mm = 68.7 mm

For β ≤ 1/10 approximately OO’ = (1/β + 2) ⋅ f + HH’.
Example 1: Video lens B1614A, focal length f = 16 mm, HH’ = 3.85 mm
L = 290 mm, S = 13.3 mm
OO’ = (L/S + 2) ⋅ f + HH’ = (290/13.3 + 2)⋅16 mm + 3.85 mm
= 384.7 mm (approximation)
Example 2: Rodagon 4.0/80, focal length f = 81 mm, HH’ = -2.5 mm, β = 1/6
OO’ = (1/β+β+2)⋅ f + HH’ = (1/6+6+2)⋅81mm - 2.5 mm = 658.7 mm

F9: Effective F-number K’, relative signal amplitude
When calculating the signal amplitude or the limit of lens resolution due to
diffraction (see F12), the F-number (focal length/ aperture diameter) has to be
replaced by an effective F-number (image range/ aperture diameter) for small
magnifications β ≤ 10. With the nominal F-number K and magnification β the
effective F-number K’ calculates to:
K’ = K⋅(1 + β)
Example: nominal F-number K = 4, magnification β = 1:
effective F-number K’ = 2⋅K = 8

F10: Edge intensity:
The edge intensity of the line scan signal is given by
the illumination and by the field angle w (see F7). Even
with homogeneous illumination the signal amplitude
decreases towards the ends of the line:
Edge intensity [%] = 100⋅ cos4(w)
w
Rule of thumb: The focal length should at least
equal the sensor length. In this case the edge intensity is > 70% of the center intensity.
w

F1: Imaging equation:
Object range and image range are related by the imaging
focal length:
From this equation formula F3 to F6 are derived.
(F11). In case of magnifications β > 6, an effective F-number K’ has to be included instead of K, (F9).
The resolution ∆ymin must not exceed the pixel pitch of the CCD line sensor.

Formulas for Lens Selection
Example: Edge intensity calculated for two different field angles with unchanged sensor length S = 28.7 and unchanged magnification β = 1/4.
a) focal length f = 50 mm
b) focal length f = 28 mm
field angle w = 13°
field angle w = 22.3°

Optical Filters
With many measuring tasks the quality of the raw data in terms of contrast
and sharpness can be improved directly through optical filtering.
Edge filters and bandpass filters suppress ambient light on directed illumination with laser or LED light.
UV-IR blocking filters suppress parts of the radiation beyond the visible wavelength region for contrast enhancement.

Illumination Components and Accessories
Illumination
Illumination techniques
Due to the high measuring frequency up to125 kHz
and a resulting exposure (integration) time of only
a few microseconds, a much higher light intensity
on the line sensor is required compared to a camera with CCD area sensor and 60 Hz frame rate for
a similar signal amplitude.
• Fluorescent tubes, linear and U-shaped, are
ideal sources of light for transillumination and
for front illumination applications with line scan
cameras (efficiency, cost to performance ratio).
The light distribution is very homogeneous
except near the electrode areas at the ends of
the glass tube.
For uniform illumination of the sensor, the
source, as with all linear sources, has to be considerably longer than the measurement range.
The electronic ballasts (HF) for the fluorescent
tubes are a special series with filter for suppression of the 50/60 Hz main frequency. The
switching frequency lies above 30 kHz.
• Excimer lamp systems are mercury-free
fluorescent tubes, equipped with internal
reflectors for increase of light efficiency.
• For even higher luminance or directed illumination (dark field illumination, see page 29,
directed bright field illumination see page 34)
linear fiber optic illumination with high-efficiency LEDs, halogen or metal vapor lamps are
used. Beneficial is a separate lamp housing with
directed heat dissipation.
• Linear LED arrays are used both for directed,
and for diffuse illumination (see page 29 and
41). With high-efficiency LEDs high luminance
and at the same time, a life expectancy of several 10 000 hours are achieved.
The type of illuminant is not only crucial for the
illumination level. Depending on the source,
different object characteristics are accentuated.
Transillumination is the most efficient illumination technique.
Application: Measuring of width and edge.
2 Front illumination: The fluorescent tube is placed as closely as possible to the measured object.
A split aperture 2.1 diminishes stray light on the CCD line sensor. For small lamp distances h the
signal amplitude on the CCD line sensor decreases almost linearly with increasing h, for larger distances (from approx. 3x lamp diameter on) it decreases with 1/h2.
1
Example: If at given distance h0 = 5 mm the CCD signal is 75 %
of the saturation exposure, the active signal amplitude results in
h1 = 10 mm: 50 %,
h2 = 60 mm: 6 %,
h3 = 100 mm: 2 %
3
With larger lamp distances h the decay of brightness is
compensated by a
3.1 cylinder lens (Fresnel, spherical or aspheric lens) or an
3.2 ellipsoidal reflector trough.

Down edge of intensity by insufficient lamp length
For uniform illumination the source of light must be clearly longer
than the measuring range. In the center of the measuring range light
portions from both sides of the source overlay. The illumination decreases towards the edges.
The distribution of intensity is not only affected by the length of the
light source, but also by the transmission and reflection characteristics of the test item (e.g. reflecting or vaguely reflecting), by the distance of the source from the measuring object and the beam characteristic of the source. The reflected beam angle with fluorescent
lamps amounts to approx. 180°, with LEDs for instance 120° and
with fiber-optic cross-sectional transformers for instance 80°. Diffusers and lens arrays in front of the source increase the edge
intensity.

Linear excimer LAMP system
LINEX® by OSRAM is a lamp system distinguished by high efficiency
and long service life up to 10,000 hours. The light source has a luminance up to 80,000 Lux
An integrated internal reflector causes an emission at an angle of 75°
(see fig. 1). Due to a pulsed DC mode with an operating frequency
> 80 KHz, the light emission is free of jitter. The luminance is 250 percent of a conventional fluorescent lamp operated in a sinusoidal AC
mode. Full luminance is reached in less than 100 milliseconds.
The spectrum of the xenon-filled light source (see fig. 2) corresponds
to a color temperature of 5400 K normal day light and is constant over
the entire service life.

Laser micro lines are used for a structured illumination of measuring objects,
e.g. for laser triangulation (see application). Laser lines are projected onto
the measurement object perpendicular to the CCD line senor. The advantage of a laser line contrary to a spot projection is a reduced demand in adjustment accuracy perpendicular to the CCD line sensor. Line generators by
Schäfter+Kirchhoff have a beam profile toward the line given by a truncated
Gaussian profile with typically 80% edge intensity.

almost constant in a working span increased

see Fig. 2).
Laser micro lines and laser macro lines:
Laser micro lines have a Gaussian beam profile
> 12 µm perpendicular to the line (Fig. 2).
Unlike laser micro lines, laser macro lines have a
depth of focus increased by a factor of 35.
Perpendicular to the line, the beam profile is
almost Gaussian within the depth of focus.
Beyond the depth of focus, side lopes appear due
to diffraction, (Fig. 3). Depending on working
distance, line widths starting with 40 µm are
achieved. For laser macro lines, the maximum
laser power is 23 mW.
Application: 3D Measurements due to combined illumination
Front illumination only
Online acquisition of height and width values with
a CCD line scan camera. The combined signals
of the front illumination and the structured laser
illumination falls onto the CCD sensor. The line
signal contains both, width and height information.
• Front illumination for 2D acquisition of length,
width, and contour.
• Structured laser illumination for 1D height
values. Laser triangulation is used for signal
evaluation.

Today, solar cells are key components of regenerative power
sources. To reach the high quality standards, manufacturing and
mounting steps are controlled automatically and with high precision. One quality and performance feature is the quality of the
collectors for current flow which are realized in silk-screen printing, the so-called grid fingers and bus bars. Caused by manufacturing process, constriction of cross section areas and even
breaks are possible. The size of solar cells of the new generation
is 150 x 150 mm and the grid finger width is 100 µm. The measuring resolution of the grid finger width is 10 µm. For this measurement task, which has to be realized online, the digital line scan
camera SK7500DTO with 7500 pixels is highly suitable.
At a measurement field width of 150 mm, the optical resolution
is 20 µm. The required resolution of 10 µm for the width measurement is reached by using a sub-pixel algorithm. To generate
a 2-dimensional image the solar cell is moved laterally to the line
scan camera. With a horizontal frequency of 5.2 kHz and a
resolution of 20 µm the transport along the measuring distance
of 150 mm is reached in 1.5 seconds.
